RIXU Agitators and Mixers are widely used for many biochemical applications, among of which is the aerobic fermentation process that requires aeration and heat transfer.

Fermentation Agitators are designed in a way to disperse the air homogenously into the whole bulk by creating fine bubbles, so that a large interfacial area is produced for efficient mass and heat exchange.

Fermentation tanks are usually tall but relatively small in diameter, thus there are multiple stages of impellers on the agitator shaft. Sometimes several agitators are installed in the same fermentation tank.
